Abstract

When verifying the metering chip, it is necessary to generate signal source excitation and write test cases, and build a simulation verification environment. The main content is the drive of incentives, the detection of output results, and the statistics of errors and data. In this paper, a signal source gain correction method is proposed, which realizes the simultaneous processing of the ratio difference between the effective value and the power value, reduces the number of ratio difference configurations in the calculation, reduces the deviation caused by the ratio difference configuration, and reduces the complexity of chip verification. And the automatic configuration of signal source gain is realized by software, which verifies the feasibility of the scheme. The experiment shows that the scheme can significantly improve the stability of signal source excitation in chip verification, reduce errors, and easily generate multiple signal source excitation through configuration.
